Tray type cable tray has the advantages of light weight, large load, beautiful appearance, simple structure, convenient installation, etc. It is suitable for both the installation of power cables and the laying of control cables. The surface treatment of tray type cable tray can be divided into plating and painting, and special anti-corrosion treatment can be carried out in heavily corrosive environment. Tray type cable tray is equipped with shield, and all accessories are common to tray type and trough type cable tray.

托盤式電纜橋架根據(jù)結(jié)構(gòu)可分為：有孔托盤、無(wú)孔托盤和組裝式托盤。

According to the structure, tray type cable tray can be divided into perforated tray, non perforated tray and assembled tray.

（1）有孔托盤是由帶孔眼的底板和側(cè)板所組成的槽形部件，或由整塊鋼板沖孔后彎制成的部件。

(1) A perforated tray is a groove shaped component composed of a bottom plate and a side plate with holes, or a component made by punching and bending a whole steel plate.

（2）無(wú)孔托盤是由底板與側(cè)邊構(gòu)成的或由整塊鋼板制成的槽型部件。

(2) A perforated tray is a groove shaped component composed of a bottom plate and side edges or made of an entire steel plate.

（3）組裝式托盤是由適于工程現(xiàn)場(chǎng)任意組合的有孔部件用螺栓或插接方式連接成托盤的部件。

(3) Assembled pallets are components that are connected to a pallet by bolts or plugs, which are suitable for any combination of perforated components on the engineering site.

他們都是用來(lái)敷設(shè)電纜的，低壓電纜和控制電纜共用同一托盤或梯架時(shí)，應(yīng)選用中間設(shè)置隔板的梯架或托盤。

They are all used for laying cables. When low-voltage cables and control cables share the same tray or ladder, a ladder or tray with a partition in the middle should be selected.

1、槽式電纜橋架與無(wú)孔托盤式電纜橋架是同一種產(chǎn)品嗎？

1. Is the trough type cable tray the same product as the hole free tray type cable tray?

2、槽式電纜橋架與無(wú)孔托盤式電纜橋架是不是都可以敷設(shè)電力電纜？

2. Can both trough type cable tray and non hole tray type cable tray lay power cables?

槽式直通電纜橋架與無(wú)孔托盤式電纜橋架是都可以敷設(shè)電力電纜；斷面、結(jié)構(gòu)形式不同而已。

Both trough type straight through cable tray and non hole tray type cable tray can lay power cables; The cross-section and structural form are different.

封閉的槽盒、無(wú)蓋的托盤還有梯架都屬于電纜橋架，三種橋架的結(jié)構(gòu)形式不同，一些性能也有差異，比如防護(hù)性以槽式好、梯架差，但通風(fēng)冷卻性卻相反。

The closed tray box, uncovered tray and ladder are all cable tray. The three types of cable tray have different structural forms and different performances. For example, the channel type has the best protection and the ladder is the worst, but the ventilation and cooling are opposite.
